Technical Field
The invention relates to the field of blood sampling devices, in particular to an animal blood sampling device.
Background
In the field of animal breeding and quarantine, it is an indispensable step to draw blood to the animal, and in the operation practice in the past, conventional blood sampling device faces some adverse factors, for example pig ear vein, birds wing vein blood sampling still use the gravity flow blood sampling mode at present, because of the structural feature of current blood sampling device, this kind of blood sampling mode operation is inconvenient to can appear polluting and extravagant phenomenon.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides an animal blood sampling device which can rapidly sample blood of animals, particularly pig ear veins and bird wing veins.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
an animal blood sampling device comprises a pump body, a push rod and a blood drawing hose, wherein the pump body is provided with a front cavity and a rear cavity, the front end of the front cavity is provided with a blood sampling port, the side wall of the front cavity is provided with an external port, a blood drawing test tube is detachably installed on the external port, the front end of the blood drawing hose extends out of the blood sampling port, the rear end of the blood drawing hose extends into the external port from the front cavity, a pump body sealing cavity is arranged at the junction of the front cavity and the rear cavity, a movable pump body sealing ball in the inner cavity of the pump body sealing cavity can seal a front channel or a rear channel of the inner cavity, the front end of the push rod movably extends into the rear cavity from the sealing cover at the rear end of the pump body, a circle of piston is fixed at the outer side of the front end of the push rod, the piston slides back in a reciprocating manner under the driving of the push rod and contacts with the inner wall of the rear, the movable push rod sealing ball in the inner cavity of the push rod sealing cavity can seal the front channel or the rear channel of the inner cavity, and the rear end of the push rod is sealed and provided with an exhaust hole.
Furthermore, a spring used for resetting the push rod is arranged in the rear cavity, one end of the spring is abutted to a spring limiting clamp on the inner wall of the rear cavity 3, and the other end of the spring is fixed on the outer wall of the push rod.
Furthermore, one end of the spring, which is far away from the spring limiting clamp, is abutted against the step on the outer wall of the push rod.
Further, the sealing cover is in threaded connection with the outer wall of the rear end of the pump body and covers the rear cavity.
Further, a pressing handle is installed on the outer wall of the rear cavity.
Furthermore, the outer wall of the rear cavity is provided with a protrusion, and the protrusion and the outer edge of the sealing cover clamp and fix the pressing handle.
Furthermore, the front end of the blood drawing hose extends out of the blood taking port and is in an expanded bell mouth shape, and the outer diameter of the bell mouth is larger than that of the blood taking port.
Further, the blood sampling test tube is in threaded connection with the external interface.
Furthermore, the tail part of the push rod is blocked by a tail cover, and the tail end of the tail cover is provided with a pressing surface for a user to press.
After adopting above-mentioned scheme, this device has apparent beneficial effect. Because the pump body is internally provided with two independent chambers of a front chamber and a rear chamber, and blood is pumped into the blood drawing hose and the blood drawing test tube through two sets of two-way movable sealing devices of the pump body sealing cavity, the pump body sealing ball, the push rod sealing cavity and the push rod sealing ball, and the pressure difference of the front chamber, the rear chamber and the outside atmosphere is made through the reciprocating sliding of the push rod and the piston in the rear chamber, so that the blood can be conveniently drawn, and the blood drawing hose and the blood drawing test tube are arranged, on one hand, the disposable use of the blood drawing hose and the replaceability of the blood drawing test tube can ensure that the pump body is clean and free from pollution, only the blood drawing hose needs to be replaced, the blood drawing device is easy to be repeatedly used, the inconvenience brought by disinfection can be reduced, the blood drawing test tube is combined with the pump body, the continuous action from the blood drawing and, reduce the pollution probability and improve the blood sampling efficiency.
